My BC 509 arrived today, purchased it w/o hearing, first impression after only a few hours listening is this DAC is very musical across the spectrum, no over emphasis on treble, midrange or bass. Has very good dynamics ,soundstage, and separation. On Peter's White's Life Story you can clearly him plucking each note, seems like you are right there with him.

Willdecide which of my 2 systems it will be in once I get some ruin-in and try it in both
